Hi, all I got a macbook yesterday and had the guys at store upgrade the RAM to 4GB instead of 2GB. I took my device today but I noticed that the battery cover when you close it is not aligned with the rest of the bottom. I mean when you move your hand over the bottom then you hit the edge of the battery cover and feel it rising over the bottom not going smoothly as one surface-yeah may be the word I am looking for is surfaced with the rest of the bottom-It is a slight thing, is it normal or should I take the computer again tomorrow to the apple store to align/ surface the battery cover with the rest of the macbook bottom..?? My best regards to you all. PS. the battery side is towards the bottom of the picture.
